Altek 422 Thermocouple calibrator – no longer in production!
The Altek 422 was designed back in 1988 and was last manufactured in 2016. The PIE 422 matches the Altek in fit, form and function with a few features bringing the design into the 21st century. It has a rubber boot and lower profile switches for protection in the field and a backlit display making it easier to use in the dark corners of your plant. Instead of the one expensive 9V battery in the Altek the PIE uses four less expensive common “AA” batteries. The PIE has the same resolution and accuracy as the Altek with longer battery life letting you calibrate more instruments between battery changes.
Advantages of the PIE 422 over the Altek 422 thermocouple calibrator
- Automatic Stepping & Ramping
- Larger Display with Backlight
Easy viewing in dark locations
- More Resistant to Accidental Damage
Rubber Boot and Stronger Switches
- Separate Battery Compartment
No more removing housing with screwdriver to replace batteries
Calibration seals remain intact
- More Accurate and Repeatable
NIST Traceable Cold Junction Sensor in isothermal block
- Easily Change Thermocouple Types
Reconfigure without resetting calibrator
- Verify Cold Junction Temperature & Output
Secondary display of compensated millivolt setting and cold junction temperature
- Includes Certificate of Calibration
All PIE Calibrators come with a free signed and dated certificate. Altek’s come only with an unsigned Statement of Calibration Practices with a certificate of calibration available for an extra charge.
Looking for more than just an Altek 422 replacement?
The PIE 422Plus Diagnostic Thermocouple & milliamp calibrator offer you not only a high accuracy temperature calibrator but also a milliamp calibrator that can source and read up to 24mA, simulate 2-Wire transmitters and also power and measure your 24V transmitters or other control instrumentation.
Similar to our PIE 334Plus, the 422Plus calibrator includes our Patented (US # 7,248,058) Current Leak Detection which protects not only your instrumentation and property from potentially catastrophic failure, but also helps ensure the safety of your most valuable assets – your people! With our Current leak detection, you can detect excess loop current due to issues such as moisture, corrosion and ground faults that can cause potentially dangerous situations.
Discontinued Altek 422
Why choose a PIE 422 instead of some other brand of thermocouple calibrator? Like the Altek, the PIE 422 has brass blocks and screws for easy attachment of thermocouple wire without connectors as well as jacks for for standard miniature thermocouple plugs. We are the same team that designed the Altek 422 and no other manufacturer has as much thermocouple calibrator experience as PIE. In addition to thermocouple calibrators PIE also manufactures a complete line of milliamp, voltage, RTD and frequency single function calibrators as well as multifunction calibrators matching and surpassing the Altek line of handheld calibrators.
When it is time for service on your Altek 422 PIE has the most experience in calibration and repair of Altek electronic calibrators. Or, if it is time to upgrade or replace a failing Altek 422 calibrator, we offer a discount on a new PIE calibrator similar to the Altek that you are replacing – in working or non working condition!
